Abstract
A rotor is adapted to be used in a reluctance motor configured to generate a magnetic field around the rotor to form magnetic circuits passing through the rotor to produce a driving force corresponding to a torque generated by changes in magnetic reluctance in the magnetic circuits. The rotor includes a first salient pole group and a second salient pole group. The first salient pole group includes a plurality of first salient poles configured and arranged to be energized simultaneously with the first salient poles being spaced apart from each other in a circumferential direction of the rotor. The second salient pole group includes a plurality of second salient poles configured and arranged to be energized simultaneously with the second salient poles being spaced apart from each other in the circumferential direction of the rotor. The first salient pole group is magnetically insulated from the second salient pole group.
